This kit contains enough HI-FLOAT to treat 50 x 9" balloons, includes pump dispenser and detailed instruction sheet. Ultra HI-FLOAT is a patented liquid solution that dries inside latex helium-filled balloons to form a coating that keeps the helium in. A single squirt inside a balloon can increase floating times by up to 25 times longer! This gives the added benefit that you can inflate your balloons a day before the party so you can concentrate on other preparations. No more last minute decorating! Note: can't be used with balloons which have plastic valves
